Spherical Bessel Functions
js(m, z)—Returns the value of the mth order spherical Bessel functions of the first kind.
ys(m, z)—Returns the value of the mth order spherical Bessel functions of the second kind.
These functions, which have no scaled versions, can be evaluated both numerically and symbolically.
Arguments
m is a real number or vector.
z is a dimensionless complex scalar or vector, z ≠ 0.
If both m and z are vectors, then they must be of equal lengths.
